This thesis addresses the analysis and optimization of preemption in multi-class loss networks. Preemption, admission control and rate adaptation, are control mechanisms that enable loss network operators to provide quality of service (QoS) guarantees for admitted calls. This research includes...

Consider a network of nodes that are deployed to monitor a common phenomenon. In many cases, the network nodes need to estimate the common phenomenon from \noisy" observations they make. Although each node can independently obtain the estimate from its own observations, it can obtain a better...
